Keyless Transmitter Button, Rear Door - Inoperative
File In Section: 8 - Chassis/Body ElectricalBulletin No.: 46-81-13
Date: February, 1995
Subject:
Rear Door Keyless Transmitter is Inoperative (Install Length of 18 Gauge Wire to Complete the 994 Circuit)
Models:
1995 Chevrolet and GMC Truck G Vans with Remote Keyless Entry System (RPO Ax3)
CONDITION
Some owners may comment that the rear door button on the remote keyless entry transmitter doesn't unlock the rear cargo door. The key transmitter has three buttons, the lock button locks all doors on the vehicle when depressed once. The unlock button unlocks the driver's door only, when depressed once, and unlocks all doors, including the rear cargo door, when depressed twice. The last button is the unlock rear door only. It is designed to unlock the rear cargo door when depressed once.
CAUSE
The # 994 circuit wire was inadvertently eliminated from the remote keyless entry (RPO AX3) module wiring harness on some 1995 model G Vans. This circuit controls the unlock operation of the remote keyless entry system. The rear doors can still be unlocked, by depressing the unlock button twice on the remote key transmitter. However, the keyless entry system doesn't unlock the rear cargo doors independent of the other doors.
CORRECTION
Install a length of light blue 18 gauge (.8 mm) wire from the "H" cavity of the remote keyless entry module connector to the body harness connector for the power door lock motor.
